Lovato’s ongoing battle with food came into focus when the teen sat down for Thanksgiving dinner with her family for the first time since leaving treatment. But, with the help of her sponsor, Lovato said she was able to make it through the dinner without throwing up: “And that’s something that I’m really proud of.”

During an after-special with MTV’s Su-chin Pak, Lovato said “it was kind of a challenge to open up to cameras [about her issues] knowing it would be in front of the world.”

“I felt really vulnerable, and I still kind of do tonight,” she said, adding. “I wouldn’t change it. I know that some girl probably needed to hear this story tonight.”

After the special aired Tuesday, Lovato tweeted her gratitude for the positive fan response on Twitter to the special.

Wow... I'm reading all of your tweets and I'm beyond speechless at all the amazing and positive feedback... Wow. So grateful!!!! THANK YOU!!
